On exploitation centres, they appear to replace cities as a place to gather resources, I think you are mostly better off with using harbours, much cheaper.
The investment in a center costs 92 money, 230 capital, 24 x10 for mfg = 562 (assuming money=capital). The return is 1 money per turn, so really has to earn itself back by allowing you to get resources you otherwise would not be able to get.
Unlike merchants where allowing for the possibility of failure the IRR is 81%, the average net return is 22 assuming mfg @ 10.
Good trading posts sending back valuable stuff like silk, opium, gold, gems etc. have an IRR in excess of 50%.
Most agriculture IRR is between 25% and 45%, opium and silk usually are over 60%.
For mines IRR is between 15% and 45% except for gold and gems which are through the roof. Coal is usually low.
Factories IRR is bwteen 50% and 75%.
This all assumes 100% efficiency and that you are buying at the base price for investment, return drops as the investment cost goes up.
A 20% increase in the cost of investment will drop a 45% IRR to 37%.
A 50% effeciency will drop a 45% IRR to 21%.
So the overall approach with a big economy is to invest in stuff, preferrably in more developed areas and hope this leads to good returns.
The way this works is if you are investing 500 a turn, then in a year you will have invested 12,000. A year later allowing for the long build times for factories you should be generating 12,000 x 20% = 2,400 extra capital a year, 100 a month. Because this is compound and assuming you have enough structures to invest in by year 10 you will have 2,500 capital a month.
